Qualifier: obviously efficiency is relative to the application.
But I would venture to say that, *in the general case*, the "most efficient" way to benefit from a second cpu, both in terms of coding time and execution efficiency, is to use either jython on a suitable jvm or ironpython on mono (when it catches up with the .net CLR in efficiency).
I say "most efficient in execution efficiency" because all of the de/serialization involved with communicating between two independent cpython interpreters, using something like pyro, would outweigh whatever performance advantage cpython might have over jython or ironpython. This becomes more pronounced as you add more and more processors into the picture.
I say "most efficient in coding time" because cpython would require you to specially write code for inter-interpreter communications, and possibly restructure your application accordingly, whereas jython and ironpython won't: the same interpreter can have threads on multiple processors, all executing simultaneously.
Although, iff your prospective machine supports System V IPC, you might want to check out PoSH.
